Outline of Final Research Achievements

This study analyzed the lip information (i.e., lip motion features, physical features of lip), and developed elemental technologies for human machine interface with high versatility. The following conclusions could be derived: (i) lip shape features of local region are useful information to classify lip shapes as similar categories, and the proposed method is useful to narrow down identification targets, (ii) focus on the variation of lip motion features can serve as efficient indices for determining the occurrence of amusement feelings, and (iii)lip motions can be significantly affected by vocalization, and high recognition rates are obtained when the same voicing state data is used for input data and registered data.
